Track Mask only works when viewing at full res v26.30

Hi ​@pegeseus & ​@New Video PRoject,

Thank you both for reporting this issue. A fix is now available in the latest 25.6 Beta builds of After Effects (look for After Effects (Beta) in the Beta section of the Creative Cloud app). If possible, please install the latest Beta and let us know if mask tracking is working when the viewer is not set to Full resolution.

Thanks again,

Hi Adobe Support Team,

I am writing to report an issue I encountered in After Effects version 26.3.

Issue Description: When using the Mask Tracker, the mask fails to follow the tracked movement properly once the tracking process is run.

My Steps:

1. Create a mask on a layer.

2. Open the Tracker panel and analyze/track the mask forward or backward.

3. The mask path does not follow the tracked object correctly during playback.

I would like to point out that this feature was working perfectly fine in version 25.6.6, so it appears to be a regression introduced in the newer release.

HERE 26.3

HERE 25.6.6

Thanks

Hi pegeseus, thanks for reaching out.

A couple of things to confirm:

1. Just to verify, could you confirm your exact AE version (Help > About)? Wanted to check whether you're on 26.3.0 specifically.

2. Did this work correctly in an earlier version (e.g., 26.2.1)? If so, that confirms this as a 26.3 regression.

3. Can you try running After Effects in Safe Mode with third-party plug-ins disabled and see if that works?

Let me know.

Thanks,

Nishu
